EMS OpenTherm emulation load compensation
Posted: Sun Nov 06, 2022 10:04 pm
Hi all
I'm steadily working towards building load compensation from Evohome to my Bosch EMS boiler.
I think the ideal would be to emulate the Bosch OpenTherm bridge device via a microcontroller board, but in the short term I'm looking at monitoring the Evohome messages via my HGI80 to infer a load level to pass to the boiler via a BBQKees EMS interface over HTTP (or similar).
Is anyone ahead of me on this? I couldn't find much here or elsewhere.
